FIEFRIGERATOR.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed August 30,1905. Serial No. 276,383.

To (L7/ 'Lu/tom, 71T? muy concern:

Be it known that we, CHARLES H. MITCHELL and JOHN F. VVINELAND, citizens of the United States of America, residing at Crafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to refrigerators, and more particularly to that class of refrigerators in which a suspended ice-containing receptacle is employed in connection with a weighing device.

The invention consists in an ice basket of novel construction, together with improved means for discharging the drip from the basket.

The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings which form part of this specification, and its novel features will be defined in the appended claims.

In the drawings, Figure l is a central longitudinal section showing the relative arrangement of the basket, and the weighing apparatus upon which the basket is hung, parts being omitted and others broken away for clearness of illustration. Fig. 2 is a fragmentary transverse section on line ac of Fig. l, Fig. 3 is a detail sectional perspective showing the construction of the ice rack, forming the bottom of the basket. Fig. 4. is a detail perspective view partly broken away, illustrating the construction of the transverse bars forming the sides of the basket, and the braces therefor, Fig. 5 is a detail perspective view of the weighing apparatus, Fig. 6 is a fragmentary sectional view through one of the bottom bars, of the basket showing the manner of supporting the same in a transverse channel bar, Fig. 7 is a detailed perspective view of a drip conductor employed in connection with the ice rack, and Fig. 8 is a plan view of a part of the ice basket showing the construction of the same along its upper edge.

The reference letter A designates the body of the refrigerator consisting of inner and outer walls a and b, said walls having a dead air chamber between them filled with insulating material c, such as cork, said space being further insulated from the ,outside atmosphere and heat by sheets of paper lining cl arranged upon the confronting sides of the walls a and b.

The refrigerator A is divided into two compartments, an upper ice compartment B, and a lower cooling compartment C.

A weighing scale is employed with our improved ice receptacle, but we have illustrated. in the drawing only such parts of the weighing mechanism as are necessary to an understanding of our improvements, and consisting of scale beams l and 2 extending diagonally across the top of the ice chamber B, and united together at their meeting point as at 3. Supplemental scale beams 4c are connected to the beams l and 2 at approximately intermediate points as at 5. The free ends of the beams 1 and 2 are suspended from the ceiling of the compartment B by connecting links 6 and the ends of the beams 4 are suspended in a similar manner. The beams l and 2 have connection adjacent their junction 3 by a loosely mounted link 7, with a balance beam 8 suspended from the ceiling of said compartment by a link 9 the other end of said beam S being connected by a rod I0 with the indicating apparatusand dial ll exposed upon the exterior of the refrigerator.

It is to be noted in this connection that the connections 3 and 5 as well as those of the link 7 and the rod l0 are flexible, being iprefand operate upon the indicator mechanism under the slightest pressure. Suspended from the free ends of the beams 1, 2 and 4 are vertical rods 12 which form the corner'posts of the ice basket. The rods l2 have rigid connection at their lower ends with the bottom of the basket said. bottom serving as an ice rack.

The ice rack is designated generally by the numeral 13 and embodies a series of transversely disposed supporting beams 14, the ends of which pass between the flanges of horizontal channel bars l5 oppositely disposed adjacent to the ends of the beams la.

For the purpose of maintaining the beams 14 in their position between the channel bars l5, we have provided a series of transversely arranged stay-bolts 16 which have the same axial disposition as the beams la and extend at regular intervals through said beams and l channel bars, the ends thereof being fastened i by nuts 17. The lower ends of the bars l2 erably universal so that said beams will give.

pass through the channel bars and end beams and are secured by nuts 18 below the flange of the channel bar.

The bottom of the basket consists of baffle bars 19, mounted upon the several supporting bars 14, each of said baffle bars 19 being provided with inclined sides 20 which serve to deflect the drip, into troughs 21 which incline downwardly from a central point 22 toward their end, thereby serving to conduct the water into conveyer troughs 23 and drain pipes 24 arranged upon the side walls of the compartment C. The troughs 21 are supported upon the beams 1.4L by projecting lingers 25 which space the troughs away from the adjacent beams, and provide an air passage 26 as indicated by the arrows in Figs. 1 and 3, through which the air flows from the ice compartment B, into the cooling compartment C.

The ice rack 13 is supported. from the suspended corner posts 12, and the superstructure of the ice basket is built about these posts and embodies the following elements. A plurality of horizontal spaced parallel bars or slats 27 are employed which extend about three sides of the compartment B, the other side thereof being occupied. by the door. These bars 27 are, disposed in a staggered relation, that is, while the two opposite end bars of each horizontal tier of slats will be in the same plane, the side bars will be in a different plane. This arrangement provides an air passage 28 between the basket and the sides of the compartment B, which leads into the cooling compartment C, and a further advantage of the construction is that the contiguous ends overlap at their junction with the suspended corner posts 12. The joint by which said bars or slats 27 are secured to the posts 12 is effected by simply bending the ends of said slats about said posts into the form of an annulus, as clearly seen in Fig. 8. The slats 27 form the side walls of the ice basket and are preferably constructed of metal, and for the purpose of bracing the same we employ a plurality of vertically eX- tending braces 29 which pass through eyes 30 formed in the sides of the slats by being struck up therefrom. i

As shown in Fig. S, the upper ends of the braces 29 are provided with enlarged heads 31 which secure the braces to the upper slats 27. The heads 31 decrease in size from the central braces to the end braces. Through seaeez eyes 33 projecting from the heads 31 a horizontal brace 32 is passed which. performs the dual function of bracing the superstructurev of the basket and of maintaining the heads 31 in. engagement therewith. The ice basket is thus Alirmly braced by the corner posts 12, the vertical braces 29 and the horizontal braces 32.

What I claim and desire to secure by Letters Patent, is

1. ln a refrigerator, an ice receptacle coniprising corner posts which project above the sides of the receptacle for suspending the latter, a bottom secured to the corner posts and serving as an ice rack, sides for said receptacle formed of horizontally disposed slats secured to the corner posts, vertically dis# posed. braces secured at their upper ends to the upper slats .of the sides by securing devices projecting from the upper ends of said. braces and resting on the upper slats, and a supplemental brace connecting said securing devices.

2. In a refrigerator, an ice receptacle cmbodying corner posts and sides, the corner posts rising above the sides for suspending the receptacle in the refrigerator, said sides formed of horizontal slats secured to said corner posts, vertical braces secured at their upper ends to the upper slats of the sides, a bottom consisting of spaced beams, drip troughs between said beams spaced away from the beams to provide air spaces, and de- V[lector plates above said troughs.

3. Ina refrigerator', a suspended ice receptacle embodying corner posts and sides,the posts rising above the sides, and the sides formed of horizontally disposed slats secured to the corner posts, vertical braces extending through eyes carried by the upper slats of the sides, heads of graduated size secured to the upper ends of said braces, a bottoni forniing an ice rack secured to the corner posts and consisting'of parallel beams, drip troughs, and deflector plates, and a discharge trough disposed to receive the drippings from said drip troughs.

'1n testimony whereof we aflix our signatures in the presence of two witnesses.
